Maryland's COVID-19 Contact Tracing App: A Comprehensive Guide
The Maryland Department of Health has launched a contact tracing app, COVID Alert MD, to help combat the spread of COVID-19. This user-friendly, voluntary tool is designed to enhance the state's contact tracing efforts, providing an additional layer of protection for residents. Let's delve into the details of this innovative app, its benefits, and how to use it.
What is Contact Tracing and Why is it Important?
Contact tracing is a time-tested public health strategy used to prevent the spread of infectious diseases. It involves identifying individuals who have been in close contact with someone who has tested positive for a contagious disease, notifying them of their potential exposure, and advising them to quarantine and monitor their health symptoms. In the context of COVID-19, contact tracing is crucial for slowing the virus's spread and protecting vulnerable populations.
How Does COVID Alert MD Work?
COVID Alert MD is built on Google and Apple's Exposure Notification system, which uses Bluetooth technology to detect when two users have been in close proximity with each other. Here's a simplified explanation of how it works:

- When you download and enable the app, it generates a random, anonymous identifier that changes every 10-20 minutes.
- Your device broadcasts these identifiers to other nearby devices with the app enabled.
- If you test positive for COVID-19 and enter the results into the app, it will notify other users who were in close contact with you during the contagious period.
- Those notified users will receive a warning that they may have been exposed to the virus and should monitor their health and consider getting tested.
It's essential to note that the app does not collect or share personal information, such as your name, location, or contact details. It only tracks proximity between devices, ensuring your privacy is protected.
Benefits of Using COVID Alert MD
Using COVID Alert MD offers several benefits to both individual users and the broader community:
- Early notification of potential exposure, allowing you to take proactive measures to protect your health and that of others.
- Reduced stigma associated with contact tracing, as the app does not reveal personal information.
- Enhanced contact tracing efforts, helping health officials identify and contain outbreaks more efficiently.
- Promotion of public health awareness and engagement in the fight against COVID-19.
How to Use COVID Alert MD
Using COVID Alert MD is straightforward. Here's a step-by-step guide:

- Download the app from the Google Play Store or Apple App Store.
- Enable Bluetooth and location services on your device.
- Open the app and follow the prompts to set up your account. You'll be asked to enter your age range and county of residence.
- Enable "Exposure Notifications" when prompted. This will allow the app to use your device's Bluetooth to detect other nearby devices with the app enabled.
- If you test positive for COVID-19, follow the instructions in the app to enter your test results and notify other users who were in close contact with you.
What to Do if You Receive a Notification
If you receive a notification that you may have been exposed to COVID-19, follow these steps:
- Monitor your health for symptoms, such as fever, cough, or shortness of breath.
- Self-quarantine for 14 days from the date of exposure, even if you don't have symptoms.
- Consider getting tested for COVID-19, especially if you develop symptoms.
